A review of the current astronomical adaptive optics projects at the Centre for Advanced Instrumentation will be presented. EAGLE is a candidate multi-object spectrograph for the European Extremely Large Telescope. Its purpose is to utilise a relatively new form of AO, open-loop multi-object AO, which allows access to the full-field of the ELT at high-spatial resolution. CANARY , recently on-sky at the WHT , La Palma, is an open-loop AO demonstrator which has helped pioneer this form of AO, and in its current configuration uses laser guide stars to tomographically reconstruct and then correct for the wavefront in an arbitrary direction. CHOUGH is instead a more precise but narrow field addition that enables CANARY for high-order AO for visible wavelength observations, and investigating novel ideas for science and instrumentation.
